Detailed Description

All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in this application and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise, the "plurality" generally includes at least two.
The words "if", as used herein, may be interpreted as "at … …" or "at … …" or "in response to a determination" or "in response to a detection", depending on the context. Similarly, the phrase "if determined" or "if detected (stated condition or event)" may be interpreted as "when determined" or "in response to determination" or "when detected (stated condition or event)" or "in response to detection (stated condition or event), depending on the context.
In addition, the sequence of steps in the method embodiments described below is only an example and is not strictly limited.
As shown in fig. 1-5, a stability augmentation system 100 of an embodiment of the present invention may include a stability augmentation instrument 20 and a load C. The stability augmentation device 20 is used for bearing the load C and stabilizing the load C. The load C may be any type of device that requires increased stability. The load C may include a sensing device that senses an environment, and the sensing device may include a photographing device, for example. The sensing device is taken as an example of the photographing device, and it is understood that the photographing device may be replaced with the sensing device. The shooting device can be used for shooting images/videos, can be a camera or a video camera, and can also be a mobile phone or a tablet personal computer with a shooting function.
The stability augmentation system 20 may include a vertical stability augmentation mechanism 22, where the vertical stability augmentation mechanism 22 may counteract or compensate for vertical jitter of the load C, which may vertically augment the load C. The vertical stability augmentation mechanism 22 includes a load mounting portion 80, the load mounting portion 80 being adapted to removably connect a load C, which may be directly or indirectly removably connected to the load mounting portion 80. The load mount 80 includes a first mechanical interface 87 for removably mounting the load C, which is removably mounted on the load mount 80 via the first mechanical interface 87, either directly or indirectly (e.g., via an intermediate component, which may include an axial cradle head). The load mount 80 includes an electrical interface 88 for transmitting control commands and/or power to the load and/or sensed data collected by the load, and the load C directly or indirectly (e.g., via an intermediate component, which may include an axial cradle head) via the electrical interface 88.
In some embodiments, the first mechanical interface 87 may be used to directly and removably connect the load C, for example, the camera may be directly and removably mounted to the load mount 80 via the first mechanical interface 87, and the electrical interface 88 may be used to directly transmit control commands and/or power to the load and/or sensed data collected by the load.
In some embodiments, the stability augmentation system 20 may include an axial cradle head 24, a load C may be detachably connected to the load mounting portion 80 by the axial cradle head 24, the load C may be mounted to the axial cradle head 24, the axial cradle head 24 may be detachably mounted to the first mechanical interface 87, the electrical interface 88 may be electrically connected to the axial cradle head 24, and the control command and/or the power and/or the sensor data collected by the load C may be transmitted to the load C by the axial cradle head 24. The axial cradle head 24 may be used to change the pose of the camera and counteract or eliminate axial shake of the camera. In some cases, axial cradle head 24 may be a triaxial cradle head. The three-axis cradle head can adjust the posture of the shooting device around a navigation direction (yaw) axis, a roll (roll) axis and a pitch (pitch) axis. In some cases, the axial cradle head 24 may also be a two-axis cradle head.
The vertical stability augmentation mechanism 22 includes a support 60. The support 60 may be used to support the vertical stability augmentation mechanism 22. The support 60 may be a hand-held support device for a user to hold, or may be a non-hand-held support device, for example, may be a component provided on an unmanned aerial vehicle, an unmanned ship, etc. for supporting the vertical stability augmentation mechanism 22 and the axial cradle head 24. The support 60 may be considered as part of the vertical stability augmentation mechanism 22, i.e., the vertical stability augmentation mechanism 22 includes the support 60, or the support 60 may be considered as a separate component from the vertical stability augmentation mechanism 22.
The stability augmentation apparatus 20 may include a processor for controlling the vertical stability augmentation mechanism 22 and/or the axial cradle head 24 and the stability augmentation apparatus 20 may further include a sensor for measuring the operating condition of the vertical stability augmentation mechanism 22 and/or the operating condition of the axial cradle head 24. The processor may be disposed on the support 60, or may be disposed at the vertical stability augmentation mechanism 22, the axial pan-tilt 24, or other location of the stability augmentation system 100. There is no limitation in this regard.
The vertical stability augmentation mechanism 22 may include two stability augmentation motors 62, and the number of the stability augmentation motors 62 may be two, so that the vertical stability augmentation mechanism 22 may utilize the stability augmentation motors 62 to drive the load C to move in a vertical opposite direction (to compensate for movement), and is mainly used for counteracting (at least partially counteracting) or compensating for shake of the load C in the vertical direction. Further, the stability of the operation of the load C can be improved, and for example, when the load C is a photographing device, a picture shake phenomenon due to photographing device shake can be improved. The counter-movement is here relative to the shaking of the load C in the vertical direction.
For example, the sensor of the stability augmentation instrument 20 obtains the magnitude of the motion or the magnitude of the change in position of the load C in the vertical direction. The sensor may include a motion sensor for sensing a vibration state of the load in a vertical direction. The processor can calculate parameters such as the rotation direction and the amplitude of the stability augmentation motor 62 according to the magnitude, and generate a control instruction according to the parameters to control the stability augmentation motor 62 to rotate. Rotation of the stability augmentation motor 62 may move the camera a corresponding distance in a reverse direction to timely compensate or cancel (at least partially cancel) the camera's shake in the vertical direction.
Illustratively, the stability augmentation motor 62 may be any type of motor. The term stability augmentation motor is used herein to distinguish it better from other motors.
Compared with passive vertical stability augmentation, the active vertical stability augmentation response time of the motor is shorter. In addition, passive vertical stability augmentation mainly depends on speed abrupt change to enhance stability, and has high requirements on speed change, so that an ideal correction effect on tiny up-and-down fluctuation is difficult to obtain. The active vertical stability enhancement by the motor is also obvious in the micro up-and-down fluctuation improvement effect. Wherein, the passive vertical stability augmentation generally utilizes an elastic member (such as an elastic member 50 appearing later) to restrict the position of the pan-tilt or the photographing device in the vertical direction, and when vertical shake occurs and the load C is shifted in the vertical direction, the elastic member 50 uses its restoring force to reset the load C in the vertical direction.
The installation position of the stability augmentation motor 62 is not limited herein as long as the power for the movement of the load C can be provided. For example, the stability augmentation motor 62 may be mounted on the support 60, and when the number of the stability augmentation motors 62 is two, the two stability augmentation motors 62 may be symmetrically mounted on the support 60.
In addition to the stability augmentation motor 62, the load mount 80, the vertical stability augmentation mechanism 22 includes a connection assembly 223, the connection assembly 223 connecting the stability augmentation motor 62 and the load mount 80. One end of the connection member 223 is connected to the load mounting portion 80, and the other end is rotatably connected to the support member 60. The link assembly 223 is rotatable about the support 60 under the drive of the stability augmentation motor 62. The load mounting portion 80 and the load C thereon are vertically movable by the rotating connection assembly 223. By controlling the movement direction, the movement amplitude and the like of the stability augmentation motor 62, the vertical movement amount of the load C driven by the stability augmentation motor 62 can be counteracted or partially counteracted by the shaking amount of the load C in the vertical direction. When the number of the stability augmentation motors 62 is two, the two stability augmentation motors 62 may be symmetrically installed at both sides of the connection assembly 223.
In the embodiment shown in the figures, the connection assembly 223 includes a four bar linkage that may include a first rail portion 222, a second rail portion 224 opposite the first rail portion 222, and a vertical bar portion 226 connected between the first and second rail portions 222, 224. One ends of the first and second cross bar portions 222 and 224 are rotatably connected to the vertical bar portion 226, respectively, and the other ends of the first and second cross bar portions 222 and 224 are rotatably connected to the fixing portion 228, respectively. The fixed portion 228 is disposed opposite the vertical rod portion 226. The first cross bar portion 222 and the second cross bar portion 224 may be disposed in parallel, and the fixed portion 228 may be considered a relatively stationary member, with the first cross bar portion 222, the second cross bar portion 224, and the vertical bar portion 226 all moving about the fixed portion 228 under the drive of the stability augmentation motor 62. The first cross bar portion 222, the second cross bar portion 224, and the vertical bar portion 226 may be considered as the respective bars of a four bar linkage. When the number of the stability augmentation motors 62 is two, the two stability augmentation motors 62 may be symmetrically installed at both sides of the first and second rail portions 222 and 224.
The stem portion 226 may be integrally formed with the load mount 80 and together form a relatively independent member. The vertical rod portion 226 may be fixedly connected to the load mounting portion 80 in a detachable or non-detachable manner. In some cases, the stator 228 may be considered a separate component from the support 60, the stator 228 may be fixedly mounted to the support 60 in a removable or non-removable manner, or the stator 228 may be integrally formed with the support 60. In some cases, the fixed portion 228 may be part of the support member 60, i.e., the support member 60 may include the fixed portion 228, and the other ends of the first and second rail portions 222 and 224 are respectively rotatably connected to the support member 60, and in particular, the other ends of the first and second rail portions 222 and 224 are respectively rotatably connected to the fixed portion 228 of the support member 60.
The two ends of the first cross bar 222 are respectively connected with the vertical rod 226 and the fixed part 228 in a rotating way, and the connection points of the rotating connection are respectively S1 and S3. The two ends of the second cross bar 224 are respectively hinged with the vertical rod 226 and the fixed part 228, and the connection points are respectively S2 and S4. The connection between the connection points S1 and S3 is S1S3, the connection between the connection points S2 and S4 is S2S4, and the connection points S1S3 and S2S4 are parallel and equal. That is, the four-bar linkage constitutes a parallelogram frame mechanism. The arrangement described above allows the angle between adjacent bars (e.g., the angle between the first cross bar portion 222 and the vertical bar portion 226, or the angle between the second cross bar portion 224 and the vertical bar portion 226) to be varied. The opposite sides always remain parallel regardless of the angle of change. The stem portion 226 may remain upright during relative movement of the sides. The first cross bar portion 222, the second cross bar portion 224, the vertical bar portion 226, and the fixed portion 228 may be considered four sides of a four bar linkage. More precisely, the lines S1S3, S2S4, S1S2 and S3S4 of adjacent connection points are regarded as four sides of the four-bar linkage.
The stability augmentation motor 62 may act on the first cross bar portion 222 or the second cross bar portion 224 to rotate the first cross bar portion 222 and the second cross bar portion 224 clockwise or counterclockwise relative to the fixed portion 228, so as to drive the vertical rod portion 226 to rise or fall. In the illustrated embodiment, the stability augmentation motor 62 is fixedly mounted to the support 60 and provides rotational power to the second rail 224 (or the first rail 222) via a crank and rocker mechanism or rocker 66.
The first rail portion 222 may include a vertical extension 2223. The second cross-bar 224 may include a vertical extension 2243. The vertical extension 2223 and the vertical extension 2243 may form a vertical housing to prevent foreign objects from entering the cavity enclosed by the four bar linkage.
The vertical stability augmentation mechanism 22 may further include an elastic member 50. The elastic member 50 may act on the connection assembly 223 to provide support for the connection assembly 223 and balance the load bearing forces. For example, the elastic member 50 may be connected to the connection assembly 223. The component of the spring force (balancing force) generated by the spring 50 in the vertical direction can be used to balance the weight force of the load, i.e. to provide a component force to the load C opposite to the weight force. In other words, the vertical stability augmentation mechanism 22 is capable of balancing the gravity of the load C by means of the elastic force of the elastic member 50. Without the provision of the resilient member 50, the stability augmentation motor 62 or other components would be required to provide a force to the connection assembly 223 to balance the weight of the load C.
The elastic member 50 may be a spring, such as a coil spring. The elastic member 50 may be mounted in various manners, for example, one end of the elastic member 50 may be mounted on the fixed portion 228 or the supporting member 60, and the other end may be mounted on the vertical rod portion 226, the first cross rod portion 222 or the second cross rod portion 224. The installed elastic member 50 can provide a force to the four-bar mechanism that resists downward rotation of the first and second rail portions 222, 224, thereby acting to balance or partially balance the weight of the load C.
Without the stability augmentation motor 62, the elastic member 50 can passively and naturally cope with the vertical shake of the load C and drive the load C to perform corresponding compensation movement.
The vertical stability augmentation mechanism 22 with the stability augmentation motor 62 and the elastic member 50 can balance the gravity of the load C, and can actively eliminate the influence of the vertical shake of the load C on the load C. It should be noted that the vertical shake generally refers to a shake having a vertical component, that is, as long as the shake of the load C has a component in the vertical direction, it may be referred to as vertical shake.
In some embodiments, the vertical stability augmentation mechanism 22 may further include a transmission member, wherein the transmission member drives the connection assembly 223 to rotate relative to the support member 60 when the stability augmentation motor rotates, and the transmission member connected between the stability augmentation motor 62 and the connection assembly 223 drives the connection assembly 223 to rotate relative to the support member 60 when the stability augmentation motor 62 rotates. The driving members may be connected to the connection assembly 223 and the stability augmentation motor 62, respectively. Further, the driving member may be rotatably connected to the connection assembly 223 and the stability augmentation motor 62, for example, a first end of the driving member is rotatably connected to the stability augmentation motor 62, and a second end of the driving member is rotatably connected to the connection assembly 223. In some cases, the stability augmentation motor 62 is an external rotor motor, the transmission may be eccentrically rotatably coupled to the external rotor of the stability augmentation motor 62, and the first end of the transmission may be eccentrically rotatably coupled to the external rotor of the stability augmentation motor 62.
The number of the stability augmentation motors 62 is two, and the number of the driving pieces is two, wherein the two stability augmentation motors 62 are arranged on two sides of the connecting assembly 223, the two driving pieces are arranged on two sides of the connecting assembly 223, a first end of a first driving piece of the two driving pieces is rotationally connected with a first stability augmentation motor of the two stability augmentation motors 62, a first end of a second driving piece of the two driving pieces is rotationally connected with a second stability augmentation motor of the two stability augmentation motors 62, and a second end of the first driving piece and a second end of the second driving piece are symmetrically rotationally connected with the first cross rod portion 222 or the second cross rod portion 224. The axes of rotation of the two stability augmentation motors 62 are substantially coincident and perpendicular to the length extension direction of the first cross bar portion 222 or the second cross bar portion 224.
In some embodiments, the transmission includes a rocker 66, a first end of the rocker 66 is eccentrically rotatably coupled to the outer rotor of the stability augmentation motor 62, and a second end of the rocker 66 is rotatably coupled to the first rail 222 or the second rail 224. The number of the stability augmentation motors 62 is two, the number of the transmission pieces is two, a first end of a first rocker of the two rockers 66 is rotationally connected with a first stability augmentation motor of the two stability augmentation motors 62, a first end of a second rocker of the two rockers 66 is connected with a second stability augmentation motor of the two stability augmentation motors 62, and second ends of the first rocker and the second rocker are symmetrically hinged to the first cross rod portion 222 or the second cross rod portion 224.
The embodiment of the present invention provides a control method of the stability augmentation system 20, and as described in the previous embodiment, the stability augmentation system 20 may include a load mounting portion 80 for detachably connecting a load, a connection assembly 223, a support member 60, an elastic member 50, and a stability augmentation motor 62. Wherein one end of the connection member 223 is rotatably connected to the support 60, and the other end is connected to the load mounting portion 80. The load mount 80 includes a first mechanical interface 87 for removably mounting the load C. The resilient member 50 is used to provide support for the connection assembly 223 and to counter balance forces to counter balance load forces. The stability augmentation motor 62 rotates the connection assembly 223 relative to the support 60 to counteract or compensate for the jitter of the load C.
When the load mounting portion 80 mounts the load C, the gravity of the load C itself acts on the connection member 223. Assuming that the center of mass of the load C is on the connection member 223, the connection member 223 receives the gravity of the downward pressure of the load C, the upward pulling force outputted from the stability augmentation motor 62, the axial force of the connection member 223 itself, and the pulling force of the elastic member 50, based on the center of mass of the load C.
It will be appreciated that if the resilient member 50 is not provided, the stability augmentation motor 62 will need to output a greater force to balance the weight of the load C, which is more energy consuming and the motor will be prone to heat. Therefore, after the elastic member 50 is installed, the vertical tension provided by the elastic member 50 can offset the gravity of a part of the load C, so that the stability augmentation motor 62 can reduce the force exerted and improve the response capability of the stability augmentation device 20.
It is noted that the pulling force in the vertical direction provided by the elastic member 50, the pulling force outputted by the stability augmentation motor 62, and the gravity of the load C cancel each other, and the pulling force in the horizontal direction provided by the elastic member 50 and the axial force of the connection assembly 223 cancel each other. Thus, the various forces experienced by the connection assembly 223 are balanced with each other, and the connection assembly 223 can achieve a balanced condition.
On this account, when the load C is detached from the load mounting portion 80, the weight of the load applied to the connection member 223 is instantaneously reduced, and the force applied to the connection member 223 is unbalanced. In the case of unbalanced stress on the connection assembly 223, if the connection assembly 223 is not controlled or interfered, the tension of the elastic member 50 can cause the connection assembly 223 to bounce instantaneously, which is easy to hurt people. To solve this problem, it is necessary to detect whether the load C is detached and to control the connection assembly 223 not to pop up when the load C is detached.
Based on the structure of the stability augmentation device 20, an embodiment of the present invention provides a control method of the stability augmentation device 20, as shown in fig. 6, the method includes the following steps:
401. it is determined whether the load C mounted on the load mounting portion 80 is detached from the load mounting portion 80.
402. When it is determined that the load C is detached from the load mount 80, the stability augmentation motor 62 is controlled to maintain the connection assembly 223 in the current position.
If it is determined that the load C mounted on the load mounting portion 80 is detached from the load mounting portion 80, the control may be switched from the stability augmentation mode to the joint angle control mode. Wherein the articulation angle control mode is used to control the stability augmentation motor 62 to maintain the connection assembly 223 in the current position.
In practice, stability augmentation motor 62 may be controlled to output a force to connection assembly 223 such that connection assembly 223 remains in the current position. The current position may be a position where the connection assembly 223 is located when the load C is detached. Specifically, proportional-integral-derivative (Proportion Integral Differential, PID) control methods may be employed to control the stability augmentation motor 62 to maintain the connection assembly 223 in the current position.
Specifically, a target joint angle corresponding to the connection assembly 223 may be determined, and the stability augmentation motor 62 may be controlled to output a force to the connection assembly 223 such that the target joint angle corresponding to the connection assembly 223 is unchanged. Wherein the target joint angle may be the angle between the connection assembly 223 and the horizontal.
The following embodiments of the present invention provide two implementations for determining whether the load C mounted on the load mounting portion 80 is detached from the load mounting portion 80, and other implementations may be designed according to requirements in addition to the two ways provided by the embodiments of the present invention, which are not limited to specific implementations.
Optionally, the load mounting portion 80 is provided with an electrical interface 88, and the load C and the load mounting portion 80 may be electrically connected through the electrical interface 88. Based on this, the process of determining whether the load C mounted on the load mounting portion 80 is detached from the load mounting portion 80 may be implemented as: detecting whether the load C breaks electrical connection with the electrical interface 88; if it is determined that the load C is disconnected from the electrical interface 88, it is determined that the load C mounted on the load mounting portion 80 is detached from the load mounting portion 80, and further, if it is determined that the load C is disconnected from the electrical interface 88 and the driving force of the stability augmentation motor 62 to the connection assembly 223 is greater than the first driving force threshold value, it is determined that the load C mounted on the load mounting portion 80 is detached from the load mounting portion 80.
It should be noted that, in some cases, the user simply disconnects the electrical connection between the load C and the load mounting portion 80, but the load C is still mounted on the load mounting portion 80 and is not removed, and the force applied by the connection assembly 223 is balanced, so that no further control or intervention is required.
In order to ensure that the load C is detached from the load mounting portion 80, the driving force output from the stability augmentation motor 62 may be further detected. If the load C is removed from the load mounting portion 80, the force applied to the connection assembly 223 is unbalanced, and for the automatic control principle, the stability augmentation motor 62 may respond to the driving force output in the vertically downward direction to offset the pulling force of the elastic member 50 in the vertically upward direction. Based on this, it can be determined whether or not the driving force of the stability augmentation motor 62 to the connection assembly 223 is greater than the first driving force threshold value, and if the driving force of the stability augmentation motor 62 to the connection assembly 223 is greater than the first driving force threshold value, it means that the load C mounted on the load mounting portion 80 is indeed detached from the load mounting portion 80.
In one possible implementation, the first driving force threshold may be represented as torque_max, and the actual magnitude of torque_max may be adjusted according to the debug result.
Alternatively, the load mount 80 may include a detection sensor for detecting whether the first mechanical interface 87 is unlocked from the second mechanical interface of the load C. Based on this, the process of determining whether the load C mounted on the load mounting portion 80 is detached from the load mounting portion 80 may be implemented as: the processor of the stability augmentation apparatus may determine whether the load C mounted on the load mounting portion 80 is detached from the load mounting portion 80 based on the sensing data detected by the detection sensor.
Alternatively, the detection sensor may be a hall sensor or a reed switch.
In practical applications, a hall sensor or a reed switch may be provided in the load mounting portion 80, and a magnet may be provided in the load C. When the magnet is far away from the hall sensor or the reed switch, the hall sensor or the reed switch cannot be triggered. When the magnet approaches the hall sensor or the reed switch, the hall sensor or the reed switch is triggered. When the hall sensor or the reed switch is triggered, the control device can determine whether the load C mounted on the load mounting portion 80 is detached from the load mounting portion 80 by detecting the state of the hall sensor or the reed switch.
After determining that the load C mounted on the load mounting portion 80 is detached from the load mounting portion 80, the stability augmentation motor 62 may be controlled to maintain the connection assembly 223 in the current position. Alternatively, the process of controlling the stability augmentation motor 62 to maintain the connection assembly 223 in the current position may be implemented as: the stability augmentation motor 62 is controlled to maintain the connection assembly 223 in the current position for a first preset period of time.
In practical applications, the stability augmentation motor 62 may be controlled to output a driving force to the connection assembly 223 such that the connection assembly 223 remains at the current position for a first preset period of time, thus allowing the user time for reaction and operation.
It will be appreciated that if the stability augmentation motor 62 continues to output driving force to the connection assembly 223, higher power is consumed and that heat may be generated by the stability augmentation motor 62 in the case of high-intensity continuous operation. Accordingly, alternatively, after the connection member 223 is maintained at the current position for a first preset period of time, the stability augmentation motor 62 may be controlled to gradually decrease the driving force to the connection member 223 to 0 so that the connection member 223 moves to the limit position under the elastic force of the elastic member 50.
In practice, the stability augmentation motor 62 may be controlled to gradually unload, i.e., gradually reduce the driving force to the connection assembly 223 to 0. Alternatively, the gradual force-relieving process may be accomplished by reducing the PID parameters. After the stability augmentation motor 62 is de-energized, the connection assembly 223 will gradually lift up under the tension of the elastic member 50 until it is lifted to the upper limit position of the joint angle due to the unbalanced force applied to the connection assembly 223.
Alternatively, if it is detected that the load C is not mounted to the load mounting portion 80 within the second period after the end of the first preset period, the stability augmentation motor 62 is controlled to gradually decrease the driving force to the connection assembly 223 to 0 so that the connection assembly 223 moves to the limit position under the elastic force of the elastic member 50.
Alternatively, the process of detecting whether the load C is mounted to the load mounting portion 80 may be implemented as: if the load C is electrically connected to the electrical interface 88 of the load mounting portion 80 and/or the driving force of the stability augmentation motor 62 on the connection assembly 223 is less than or equal to the second driving force threshold value, it is determined that the load C is mounted to the load mounting portion 80.
In one possible implementation, the second driving force threshold may be represented as torque_min, and the actual magnitude of torque_min may be adjusted according to the debug result.
Further, to ensure that the load C is indeed mounted to the load mounting portion 80, it may alternatively be determined that the load C is mounted to the load mounting portion 80 upon detecting that the load C remains electrically connected to the electrical interface 88 of the load mounting portion 80 for more than a preset period of time.
Alternatively, if it is determined that the load C is not mounted to the load mounting portion 80 within the third period of time after the load C is detected to be detached from the load mounting portion 80, the stability augmentation motor 62 is controlled to gradually decrease the driving force to the connection assembly 223 to 0 after the connection assembly 223 is maintained at the current position for the third set period of time, so that the connection assembly 223 is moved to the limit position by the elastic force of the elastic member 50.
In practical application, when it is determined that the load C is detached from the load mounting portion 80, and if the load C is not mounted back to the load mounting portion 80 for a third period of time, the stability augmentation motor 62 is controlled to gradually reduce the driving force to the connection assembly 223 to 0, so that the connection assembly 223 moves to the limit position under the elastic force of the elastic member 50. In one possible implementation, the third time period may be denoted as t_max, for example, and the third time period may be set to 30s, for example, and of course, the third time period may be adjusted according to actual requirements.
It will be appreciated that in some applications, the user removes the load only to replace another load, rather than actually removing the load, and thus the user may be left with sufficient time to replace another load, which may be a third duration. When the third duration is reached and the user has not yet installed the load back into the load mount 80, indicating that the user does not need to replace the load, the stability augmentation motor 62 may be controlled to gradually unload the force.
Accordingly, if it is determined that the load C is mounted to the load mounting portion 80 within the second period after the end of the first preset period, the stability augmentation motor 62 is controlled to rotate the connection assembly 223 relative to the support 60 to offset or compensate for the vertical shake of the load.
Or, alternatively, if it is determined that the load C is mounted to the load mounting portion 80 for the third preset time period, the stability augmentation motor 62 is controlled to rotate the connection assembly 223 with respect to the support 60 to counteract or compensate for the vertical shake of the load.
If the load C is detected to be mounted on the load mounting portion 80 within the third period of time, it indicates that the user has replaced the load, and the stability augmentation motor 62 may be controlled not to perform the force unloading, but to perform the normal stability augmentation operation, that is, to control the stability augmentation motor 62 to rotate the connection assembly 223 relative to the support member 60 to offset or compensate for the vertical shake of the load.
Alternatively, if it is determined that the load C is mounted to the load mounting portion 80 and the startup stability augmentation information is obtained, the stability augmentation motor 62 is controlled to drive the connection assembly 223 to rotate from the limit position to the preset position relative to the support 60, and the stability augmentation motor 62 is controlled to drive the connection assembly 223 to rotate relative to the support 60 to offset or compensate for the shake of the load C in the vertical direction.
It should be noted that, when the stability augmentation device 20 detects that the load C is mounted on the load mounting portion 80 and obtains the startup stability augmentation information, the stability augmentation motor 62 may be controlled to drive the connection assembly 223 to rotate from the limit position to the preset position relative to the support 60 according to the startup stability augmentation information, and the stability augmentation motor 62 may be controlled to drive the connection assembly 223 to rotate relative to the support 60 to offset or compensate for the shake of the load C in the vertical direction.
The preset position may be a position designated by a user, and the user may input the designated position to the stability augmentation apparatus 20 according to the personal usage habit of the stability augmentation apparatus 20. This allows for preferential control of the rotation of the connection assembly 223 to the designated position when the stability augmentation instrument 20 is awake.
Alternatively, in response to the stability augmentation motor 62 gradually reducing the driving force to the connection assembly 223 to 0 or the connection assembly 223 moving to the extreme position, the stability augmentation device 20 may be controlled to enter the sleep mode. Accordingly, in the sleep mode, if it is determined that the load C is mounted to the load mounting portion 80 and the startup stability augmentation information is obtained, the stability augmentation motor 62 is controlled to drive the connection assembly 223 to rotate from the limit position to the preset position relative to the support 60, and the stability augmentation motor 62 is controlled to drive the connection assembly 223 to rotate relative to the support 60 to offset or compensate for the shake of the load C in the vertical direction.
After the stability augmentation electric motor 62 is de-energized, the stability augmentation instrument 20 may be controlled to enter a sleep mode to reduce power consumption. When the user wants to reuse the stability augmentation instrument 20, a load C may be installed and wake-up the stability augmentation instrument 20. When the user wakes up the stability augmentation device 20, the stability augmentation device 20 may acquire startup stability augmentation information, and then the stability augmentation device 20 may operate the stability augmentation motor 62 according to the startup stability augmentation information.
Optionally, the stability augmentation device 20 may further comprise interaction means for detecting user operation. The process of acquiring the startup stability enhancement information can be implemented as follows: and if the start stability augmentation operation of the user on the interactive device is detected, generating start stability augmentation information.
For example, a wake-up key may be set in the stability augmentation device, the wake-up key may be the interaction device, and the start of the stability augmentation operation may be a click operation of the wake-up key. When the user clicks the wake-up button, the sleep mode may be switched to the stability augmentation mode.
By adopting the invention, when a user removes the load from the load installation part, the load can be timely detected to be removed from the load installation part, and the stability augmentation motor is further controlled to output driving force to the connecting component, so that the connecting component is kept at the current position, the connecting component and the load installation part cannot be pulled up, the user cannot be injured, and the safety of the user is ensured.
